How Can I Trigger an NI-RFSA Acquisition With a Marker Exported From NI-RFSG?

I'm interested in exporting a marker event from a NI-RFSG session in a given time and export it so it can be used to trigger an NI-RFSA acquisition. How can I do that?

On the NI-RFSG session:
  1. Configure a Marker using niRFSG Export Signal.vi and set it to be exported through PXI_Trig0:

  1. On the niRFSG Write Script.vi add the marker and set it to be generated on a given sample, in this case, sample 0:

On the NI-RFSA Session:
 
  1. Use niRFSA Configure Digital Edge Ref Trigger.vi to read the marker sent by the NI-RFSG session. Make sure that the source matches the output terminal of niRFSG Export Signal.vi:

Applying the above steps is one of several ways to get your NI-RFSG session to export your marker from to a PXI_Trig line on a given moment and then have the NI-RFSA session read the marker and control the acquisition.
